> Then after a period of time, typically 3-4 years, but not more than 5 years, the restrictions lapse, and the source code automatically converts to an Open Source license, in our case Apache 2.0.

I’m not familiar with this type of license. Any idea how/when this time frame is decided? Is it 3-5 years from software release?

I guess I’m confused by the use of “automatically converts” with a vague timeline. If it’s automatic why isn’t the time of “automatic” conversion more definitively known? What’s the event that triggers the change?
